....from taking my blood? I had my 17 week blood draw yesterday where they will test the baby for Downs Syndrome, Spina Bifida, etc.
But how can they tell if the baby has these just from taking my blood? I was going to ask and then from the trauma of all the pokes trying to find a vein that would cooperate I lost my train of thought
I'm not sure really. But it's in the DNA in your blood. I'm sure it's very complicated to explain the exact way it's done.
Just know that they have been doing it for decades and it's a very accurate test.
